Real Madrid goalkeeper Keylor Navas is set to miss Saturday's game at Getafe with a hamstring problem and could also be sidelined for Tuesday's Champions League match at home to Tottenham.
Costa Rica international Navas suffered the injury during the draw with Honduras on Saturday that clinched their place at the World Cup.
He was released from the squad ahead of Tuesday's game against Panama, and Costa Rica doctor Alejandro Ramirez told his federation's official website: "After the game against Honduras, Keylor felt an issue in his right leg.
"A series of tests were carried out which showed he had a soft tissue strain in his right hamstring muscle "
Madrid back-up keeper Kiko Casilla is now set to face Getafe on Saturday.
A Madrid statement on Tuesday said: "Following his return from international duty, Keylor Navas worked out indoors "
" Gareth Bale, Mateo Kovacic and Dani Carvajal continued with their respective recovery programmes."
Meanwhile, Madrid's Germany midfielder Toni Kroos is recovering from the rib problem that saw him miss his country's final qualifier this week.
The international break has allowed Karim Benzema, Marcelo and Theo Hernandez to recover completely from recent injuries, with all three expected to feature in the squad for the Getafe game.
